Start with pulling the battery and power, then hold the power button in for about 30-40 seconds. Then plug the power back in (still no battery). Try to power up the computer. If it boots, shut it down and put the battery in and try again. If it boots the issue was cleared. If it boots with the power cord but not with the battery added, you have a battery issue.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall.
ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.
Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

It is most likely that your battery is shot, but you could try unplugging your power supply, popping out your battery, and carefully clean the contacts on both the battery and where the battery connects to your laptop.

The only thing you can really do in this case is call gateway and see if they can repair this. it seems like something internal. Hopefully the computers are still under warranty. Sorry for the bad news.

I experienced this problem last night, and seemed to have fixed it this morning.

SYMPTOMS: HP Pavilion dv9000, Win Vista x64 Ultimate. Running on battery, battery level became critical; windows went into 'Hibernate' mode. Upon plugging in to mains power, and resuming the Windows session, the Wireless is still disabled, no matter what position the switch is in.

POSSIBLE CAUSE: Critical battery switches off the wireless network card to preserve power. Motherboard seems to log this status but when re-connecting to mains power the card does not receive power again. Uninstalling the driver and getting Windows to re-install automatically upon re-boot does not work.

SOLUTION: Charge up the battery whilst the computer is running. You can charge it to a substantial level, say, above 25%. Disconnect mains power so that your laptop is running on battery only. Set your wireless switch to OFF (this is usually to the left position, away from the orange indicator). Now run your computer down to the critical battery level again (perhaps overnight). In the morning when you press the power button, the 'CHARGE' indicator (looks like a lightning bolt) on the front of the laptop should flash quickly, indicating that there is no charge in the battery. Remove the battery from the laptop's underside. Wait a couple of seconds, then press and hold the power button for 30 seconds. Keeping the battery off the laptop, reconnect mains power. Boot up your PC. When at the Windows desktop and all your startup programs have finished loading, switch your wireless on (to the right position). You should now have a blue light, and wireless should once again be working. You can now re-insert your battery. You might have to setup your wireless network connection again as mine seemed to be 'lost', but at least hopefully the main problem is now fixed.

You have a desktop PC where the mouse will not work while it is on the mousepad?

If that is the case, check this: If it is a optical/laser mouse (a light on the bottom, instead of a ball) make sure your mousepad is not made from a reflective material like plastic. Try a fabric pad.
